Several times in Earth's history, rapid global warming occurred, apparently spurred by amplifying feedbacks. In each case, more than half of plant and animal species became extinct. New species came into being over tens and hundreds of thousands of years. But these are time scales and generations that we cannot imagine.
What dinosaur traits are missing from an ostrich? The ostrich has a toothless beak, but there are mutations that cause teeth and claws to come back to their mouth and limbs. You need to replace the feathers with scales, but there are no feathers on their legs and feet, so you just need to make its whole body like its legs are.
No disrespect to people that don't use music theory or don't know it. It does help to be able to figure out what key a song is in, even though with your scales you can figure it out so you can set your Auto-Tune right. So many songs with Auto-Tune are off or have the wrong note playing on the 808. And they pass it off as being hood.
There are thousands of ragas, and they are all connected with different times of the day, like sunrise or night or sunset. It is all based on 72 of what we call 'mela' or scales. And we have principally nine moods, ranging from peacefulness to praying, or the feeling of emptiness you get by sitting by the ocean.
